Effects of a Pain Catastrophizing Induction on Sensory Testing in Women with Chronic Low Back Pain: A Pilot Study

Figure 3

Mechanical allodynia response over time by experimental condition. The interaction of time and condition on mechanical allodynia, controlling for baseline trait PCS and baseline current back pain intensity, was significant (unstandardized β = −6.20, ), with allodynia being significantly greater in the induction condition following the experiment.
